@giorgiocas Opera doesn't have such feature, so you would need to find out an extension, if you are on desktop, or a third party app on mobile.
I don't have any to recommend.

@burnout426 man, I made a point of logging into opera just to thank you for the explanation. it was the only good explanation I found on the internet to solve this problem, and it worked. I've been using opera for years and it has always been the best browser for me, but recently it has been heavy on my computer, even though I have already formatted it. I'm testing the edge. anyway, you were awesome, thank you very much.
